Tantaly Auto Temperature Control USB Heating Rod
1. Before using the heating rod, check for cracks, deformations, or breaks in the product and power cord.
2. Insert the USB plug of the heating rod into a 5V - 2A adapter interface for power supply.
3. Use an appropriate amount of lubricant and slowly insert the heating rod into the tunnel of the doll.
4. Once the heating rod is activated, the indicator light will remain steady. When the temperature reaches 112℉, the indicator light will go out, indicating the cessation of operation. Below 112℉, the indicator light will reilluminate, restarting the heating process.
5. After heating is complete, unplug the adapter first, and then unplug the USB plug.
6. After use, wait for the product to cool to room temperature, and clean with water or wipe with alcohol.
Precautions
1. Please use a 5V - 2A output adapter for power supply.
2. The connection between the heating rod and the wire can be rinsed with water but should not be immersed in water.

4. Do not contact corrosive disinfectants, cleaning agents, or solvents.
5. After cleaning and drying, store the product in a cool and clean place.

Real and Cozy Tunnel Experience
Tantaly's heating rod rapidly reaches a temperature of 112°F within a short time. The aluminum alloy material at the top enhances thermal conductivity, warming the depths of the doll's passage. Just 5-10 minutes provide you with a snug enveloping sensation.

Thoughtful Safety Measures
The product features an internal electronic thermostat board; when heated to 112°F, the indicator light goes out, and if the temperature drops below 112°F, the light rekindles. Even if the plug is left connected for an extended period, the temperature won't rise excessively.

Waterproof Design
With an IPX4 waterproof rating, it can withstand water flow, and the wire interface has been waterproofed to prevent moisture ingress, ensuring longevity.

Not for fish tanks, lol
As a newbie I didn't know about the need, or at least benefit, of these things while looking at dolls and other toys until I saw them in suggested bundles and related products. It makes sense as soon as you see one but not something I would have thought of on my own. They looked simple. Plug it in and it goes up to whatever temperature they're rated for. It reminded me of a fish tank heater and I remembered one I had being able to control the temperature so I went and searched for adjustable fish tank heaters because I thought "what if I only need to warm it a little?" Ha! Wrong! The tank heater arrived, I plugged it into the outlet, set it to about 98ºF, body temperature, and waited a minute. Luckily I didn't leave it sitting on anything or had inserted it yet because it got very hot very fast. I could feel the heat coming off of it from a few inches away so I touched it to a non-tantaly handheld toy and it smoked instantly. Eating away at the material. I pulled it away and turned all the way down to the lowest 60ºF. It was still very hot so I unplugged it and balanced the end off of a table until it was cold. Minutes later it came to me that they're for heating gallons of cold water to that temperature so the surface temperature must be much hotter. (>_< ) Anyway, I ordered this with Daisy who I'm very glad wasn't here yet to endure the torture of a tank heater. I used the proper device on each of Daisy's holes. It heated them to the perfect temperature. Didn't melt her or burn my hands or anything. That's where the title comes from. Don't stick fish tank heaters in your doll and you probably should use this for fish. Btw it worked with a portable battery pack that's used to charge phones and stuff. If you can't or don't want to bring your doll near something you can plug the USB into, plug it into one of those anywhere you want.
Does not work at all
Plugged it in and waited over an hour, checking frequently, and it never heated up. Do not buy this.

It helps
I think it is worth getting. It won't make your sex toy as warm as a human hole, but it does take the experience of using your toy up a level.
